[No...] Posted July 23, 2021 Share Posted July 23, 2021 Is there a quick way to generate a space point under a precise angle in a certain depth on a cylindrical surface? I usually creat space point sets (e.g. 3 along a curve segment) on a section curve and delete the surplus ones, but I can't do that here as I need a really precise angle and the correct depth. See attached drawing. The point has to be 22 mm deep at 56 degrees. Link to comment https://qualityforum.zeiss.com/topic/12432-space-point-on-cylinder/ Share on other sites More sharing options...
[Ro...] Posted July 23, 2021 Share Posted July 23, 2021 Not sure about a quick way. That's kind of subjective. You can create a theoretical line and intersect it with the cylinder to get the x/y/z location. Then create a space point and key in the x/y/z data and calculate the IJK values with a little math (sin/cosine of the angle) to get the correct vectors.

[Ja...] Posted July 23, 2021 Share Posted July 23, 2021 click on the space point and Use 'feature representation editor' in the 'resources' menu > change "default" to "modify" > change representation of the point from cartesian to cylindrical co-ordinates. Now you can enter radius, precise angle and depth. Link to comment https://qualityforum.zeiss.com/topic/12432-space-point-on-cylinder/#findComment-62222 Share on other sites More sharing options...
[Ro...] Posted July 23, 2021 Share Posted July 23, 2021 That's another good method, Andreas. Then the created space point x/y/z values will be 0 and the nominal vector 1 or-1 depending on your approach direction.

[No...] Posted July 26, 2021 Author Share Posted July 26, 2021 Please sign in to view this quote. I tried this and I wish it would work (that's what I would call a quick way). But unfortunately it doesn't, since the radius, angle and depth values don't correspond with the base alignment, but only with the local element coordinate system. @ Robert & Andreas: Thnks for pointing me in the right direction! Now that you mentioned these options, I was like "of course!" 😮 . But Friday afternoon my brain was already in standby mode...
